Cortez rainbow wrasse Profile

The Cortez rainbow wrasse (Thalassoma lucasanum) is a brightly colored fish, featuring a blend of blue, green, and yellow hues, particularly vivid in males. It originates from the Eastern Pacific, specifically from the Gulf of California to Peru and the Galapagos Islands. This species has a slender, elongated body typical of wrasses, and displays sexual dimorphism with males being more colorful than females. Although it inhabits tropical and subtropical marine environments, it is not particularly well-known in the aquarium hobby, partly due to its specific care requirements and greater prevalence in its natural habitat.
